Google said today that it had agreed to buy British artificial intelligence start-up company DeepMind for an undisclosed amount.
"I can confirm that the acquisition has indeed gone ahead but unfortunately we are not commenting beyond that for now," a Google spokeswoman said.
Reports put the deal at between $400-500m (€292-365m).
DeepMind describes itself as "a cutting edge artificial intelligence company" which combines "the best techniques from machine learning and systems neuroscience to build powerful general-purpose learning algorithms".
Artificial intelligence can help computers "think" in ways similar to the way humans think and help solve problems.
Last year, Facebook unveiled a partnership with New York University for a new centre for artificial intelligence, aimed at harnessing the social network's massive trove of data.
